i haven't do anything with it, when i just add that dependency, my apps give me this error. Here is my complete pom.xml :

here is my controller :
package com.movie.db.KotakKantorMovieDB.controllers;
import com.movie.db.KotakKantorMovieDB.models.Customer;
import com.movie.db.KotakKantorMovieDB.repository.CustomerRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
@RestController
public class CustomerController {
@Autowired
private CustomerRepository repository;
@GetMapping("/customer")
public Customer findCustomer() {
return repository.findByFirstName("cactuspot");
}
@PostMapping("/addcustomer")
public Customer addCustomer(@RequestBody Customer newCustomer ) {
return repository.save(newCustomer);
}
}
here is my model :
package com.movie.db.KotakKantorMovieDB.models;
import org.springframework.data.annotation.Id;
public class Customer {
@Id
public String id;
public String firstName;
public String lastName;
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
}
and here is my repository :
package com.movie.db.KotakKantorMovieDB.repository;
import java.util.List;
import com.movie.db.KotakKantorMovieDB.models.Customer;
import org.springframework.data.mongodb.repository.MongoRepository;
public interface CustomerRepository extends MongoRepository<Customer, String> {
public Customer findByFirstName(String firstName);
public List<Customer> findByLastName(String lastName);
}
what did i missed here? i is there some dependency that i shouldn't use whtn i add spring-boot-starter-data-rest
?
Solution
i trying to delete :
<dependency>
<groupId>com.jayway.jsonpath</groupId>
<artifactId>json-path</artifactId>
<scope>test</scope>
</dependency>
this dependency, and it solved the error, i dunno why this dependency cause the error, and i dunno why this dependency is needed, i run my apps and it just work fine without this dependency. maybe there is something to do with HATEOAS. If somebody can explain it to me, i will accept it as an answer
